Question

How do you simplify and find the excluded values of `(x^2 + 2x)/( 3x - 5)`?

Answer 1

`(x(x+2))/(3x-5)tox!=5/3`

Explanation:

`"this rational function can only be simplified by factoring"`
`"the numerator"`

`"take out a "color(blue)"common factor of x"`

`rArr(x(x+2))/(3x-5)`

`"the denominator cannot equal zero as this would"`
`"make the function undefined"`

`3x-5=0rArrx=5/3larrcolor(red)"excluded value"`
